HUTCHMED Highlights Sovleplenib Phase III ESLIM-01 Study and Hematological Malignancy Programs Data to be Presented at the upcoming EHA2024 Congress

 

Hong Kong, Shanghai & Florham Park, NJ - Friday, May 17, 2024: HUTCHMED (China) Limited ("HUTCHMED") (Nasdaq/AIM:HCM; HKEX:13) today announces that topline and subgroup results from the ESLIM‑01 Phase III study of sovleplenib, as well as new and updated data related to novel investigational hematological malignancy therapies HMPL-306, HMPL-760 and tazemetostat, will be presented at the upcoming European Hematology Association ("EHA") Hybrid Congress, taking place on June 13-16, 2024 in Madrid, Spain and online.

 

ESLIM-01 is a randomized, double-blinded, placebo-controlled Phase III trial in China of sovleplenib in adult patients with primary Immune Thrombocytopenia ("ITP") who have received at least one prior line of standard therapy (NCT05029635). In 188 patients randomized to receive oral sovleplenib or placebo, sovleplenib demonstrated a clinically meaningful early and sustained durable platelet response in patients with primary ITP with durable response rate of 48.4% compared to zero with placebo (p<0.0001). The median time to response was 1.1 weeks with sovleplenib. It demonstrated a tolerable safety profile with grade 3 or above treatment-emergent adverse events (TEAEs) in 25.4% of patients with sovleplenib and 24.2% with placebo. Sovleplenib also significantly improved quality of life in physical functioning and energy/fatigue (p<0.05).

 

Most patients were heavily pretreated with a median of four prior lines of ITP therapy and a majority (71.3%) of the patients had received prior TPO/TPO-RA[1] treatment. Further post-hoc subgroup analysis of the study demonstrated consistent clinical benefits across ITP patients regardless of prior lines of ITP therapies or prior TPO/TPO-RA exposure, regardless of TPO/TPO-RA treatment types and number of prior regimens.

 

In addition to the promising data in ITP, results from Phase II part of the ongoing ESLIM-02 Phase II/III study (NCT05535933) of sovleplenib for warm antibody autoimmune hemolytic anemia (wAIHA) will also be presented at the congress demonstrating encouraging hemoglobin (Hb) benefit compared with placebo, with overall response rate of 43.8% vs. 0% in the first 8 weeks, and overall response rate of 66.7% during the 24 weeks of sovleplenib treatment (including patients that crossed over from placebo). A favorable safety profile was also demonstrated.
